Since the TDP hasn't changed, it's pretty clear that Intel is recovering 6-core i7-39xx units that have 1 or 2 defective cores and selling as 4-core. AMD has done this with their many Core units as well.Reply

Actually all the six core socket 2011 chips are binned 8 core chips. I suspect yields are good enough that Intel wouldn't need to cripple additional cores on their larger chips. Various reports are indicating that this is a new die 294 mm^2 in size.Reply

Seen that type of hand writing before on this site, so I doubt it's Intel, but if it was. I wonder how much that person gets paid just to write model numbers on ES CPUs to be sent out for reviews.Reply

That's true, but since we don't have any details of IVB-E, I think it would be premature to list it as a reason. We don't know when it will be out. We don't know how fast it will be. There is no guarantee that IVB-E will bring more than four cores into the ~$300 market, which would again make it similar to LGA 1155 offerings. Reply

2600K is still better than 3820, since you can overclock. A bit of a waste to pay hefty price for LGA2011 mobo and not get 3930K. And if you *really* need the memory advantage, then Sandy Bridge Xeon is a better way to go. This 3820 chip is made for a very very small niche of folks. :)Reply

You can overclock the 2600k with the open multiplier, but if you read the articles on Anandtech about SNB-E, you will find out that the 3820 is partially unlocked and can also overclock via BCKL. "By default Sandy Bridge uses a 100MHz bclk, but SNB-E allows for 125MHz, 166MHz and 250MHz options as well." I doubt there will be great differences between the two, overclock wise.Reply

I still can't find somewhere to buy the i7 3820. Intel says it's released, but Newegg and Tigerdirect don't list it. Amazon still indicates 1 to 2 months. Some other retailers are saying maybe next week at the absolute earliest. Stories in Europe and Asia indicate they already have the chip. Did these things get shipped to the US via boat instead of jet? Also, I have yet to find someone selling the CPU below $315. Most retailers are charging $330 and up.

I'd like to buy an i7 3820. I'm replacing my current main machine which is still running a C2D P8400. The i7 3770 is still two months away and should have the same price tag and performance. I don't see the need to wait for the slightly lower power consumption. It's getting rather annoying to have to wait and wait and wait for Sandy Bridge-E. The shortages and delays are really bad.Reply

I ordered mine yesterday (Monday 2/13) from http://www.seaboom.com/. They called me today and said it was shipping this afternoon. I've never ordered from them before, but it's a sealed boxed product, and is apparently shipping directly from Intel, so I figured what the heck.Reply

I would buy one today if i couod find one for sale.I just burnt out my x58 i7 920 board.I use applications, cad, fea, revit, that benefit from memory. I could get a z68 setup much cheaper, but the lack of memory is a downfall. Reply
